WALTER BILLS, OF SOUTH MELBOURNE, VICTORIA, AUSTRALIA.

COILER FOR WlRE-WEAVING MACHINES.

SPECIFICATION forming part of Letters Patent No. 754,118, dated March 8, 1904.

Application filed October 22, 1901. Serial No. 79,538. (No model.)

To all whom it may concern:

Be it known that I, WALTER BILLS, wire weaver, a subject of the King of Great Britain, residing at Miller street, South Melbourne, in the State of Victoria, Commonwealth of Australia, have invented an Improved Coiler for Wire -VVeaving Machines,of which the following is a specification.

The object of my invention lies in the construction of a coiler that will perform the work of coiling one wire or a plurality of wires laid side by side with the greatest facility and with a minimum wear; and to this end the mandrel must be made of tapering form from a point near its delivery end to its receiving or feed end, while the forming-coil itself is made of a simple round Wire coiled ontothe mandrel, so that it must fit it snugly, which may be done by any intelligent workman.

It will be very readily understood that with a forming-coil of round wire the bearing-surface of the coil on the mandrel is merely a line, while the bearing-surface for the wire is a convex one, forming, with the mandrel, a Wedge-shaped space in which the wire or one .of the wires travels, the tendency of which is to crowd the wire or wires up alongthe taper of the mandrel and finally off the same.

To reduce the Wear of the mandrel to a minimum, I make the forming-coil of ametal softer than said mandrel, the coil being replaceable when worn out not only with the greatest facility, but at a trifling cost.

That my invention may be fully understood I will describe the same in detail, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of the headstock of a wire-weaving machine fitted with my invention. Fig. 2 is a side elevation,

I drawn to a larger scale, showing the coiler detached from the machine. Fig.- 3 is a side elevation of the spindle or rotating portion of the coiler. Fig. l is a similar View of the tapering coil or spiral, which fits closelyaround said spindle. Fig. 5 is a view of the coiler, showing the stationary forming-coil in section.

The same letters of reference indicate the same parts in all the figures.

A represents a slightly-tapering spindle or mandrel adapted to be gripped firmly between the jaws of a suitable chuck B upon a spindle capable of being revolved at a rapid rate in the bearings of a suitable head-stock, as shown, while C represents a helically or spirally wound stout wire coil which fits closely around the tapering spindle A and is held firmly against rotation in a rest or holder D, mounted axially in line with the chuck B and preferably carried by the same casting or bedplate as the rest of the head-stock.

The coiler is set in the head-stock with its larger end outward, the wires being first fed onto the smaller end and delivered coiled from the larger or outer end. The material of which it is formed must be softer than the spindle in order to work most effectively, and it has been found that tinned-iron wire upon a mild-steel spindle gives good results.

If the forming-coil is made of the same material as the spindle, the latter becomes scratched or worn out irregularly, and in practice I have found that this causes one or more of the multiple Wires to drop behind or lag, and to avoid this the constant attention of a skilled operator is necessary. By making the forming or coiling Wire or track of a softer metal than that of the spindle this defect is obviated until the forming or coiling wire is considerably Worn, when it is removed and another substituted.

With a coiler constructed as specified it is possible to simultaneously coil and weave from one to half a dozen or even more wires.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a self-feeding wire-coiling machine, a coiling device comprising a revoluble cylindrical mandrel of gradually-increasing diameter from its feed toward its delivery end and a stationary forming-coil, the convolutions of which have rounded edges, said coil fitting said mandrel snugly and having suflicient space between its convolutions to admit of the passage of a plurality of wires side by side, substantially as set forth.
